Correlations between the measured percentages of affected BSA. Correlation analysis between VES and VASI for live scoring of patients (=session 2) (a) and scoring on pictures of consecutive patients and patients with extensive vitiligo (session 3 (b) and session 5 (c)). Correlations between live scoring (=session 2) and picture scoring (=session 3) for (d) VES and (e) VASI and between scoring of patients with extensive vitiligo at two time points (=sessions 5 and 6) for (f) VES and (g) VASI. BSA, body surface area; VASI, Vitiligo Area Scoring Index; VES, Vitiligo Extent Score.
